Broadleaf-crop grass-weed program: quizalofop-P-ethyl
The crop, grass species and crop-safety conditions must come from the destination-market label. This page helps procurement teams compare the confirmed formulation and supply requirements.
How to verify usage guidance for Quizalofop-P-ethyl
Start with the exact product label approved by the authority in the country of use. The FAO approved-label directory explains where to find national label records. Record the directions below before comparing a supplier's offer.
Label checklist for a grass-weed program in broadleaf crops
- Exact product and registration
- Match the product name, registration number, registrant and current label version to the destination-country authority record. A label from another market is only a reference.
- Crop and grass species
- Quizalofop-P-ethyl is a selective grass herbicide; it does not control broadleaf weeds or sedges. The label lists the broadleaf crops and grass species covered.
- Isomer identity
- Quizalofop-P-ethyl is the enriched active isomer, while quizalofop-ethyl is the racemic form. Their concentrations and registrations are not interchangeable.
- Grass stage and conditions
- Record the grass growth stage and the growing-condition statements on the label before relying on a timing.
- Tank mixes
- Follow only the mixtures the label lists; some broadleaf herbicide partners can reduce the activity of grass herbicides.
Quizalofop-P-ethyl is an ACCase inhibitor in HRAC Group 1. Group 1 resistance is documented in several grass weeds, so record earlier ACCase use. Check the HRAC herbicide mode-of-action classification and local resistance advice. A classification is not crop registration or evidence that a product will work in every program.

Quizalofop-P-ethyl usage questions
Will quizalofop-P-ethyl control broadleaf weeds?
No. It is a Group 1 grass herbicide. Broadleaf weeds need a separately registered product, and any combination must be one the labels permit.
Is quizalofop-ethyl the same product?
No. Quizalofop-P-ethyl is the enriched active isomer. Match the exact name and concentration on the registration before comparing offers.
What should an importer prepare before ordering the EC?
Send the registration or label reference, crop list, required concentration, pack size and label language. Ask for the specification, SDS and a batch-specific COA.
